Abstract

The aim of this work was to evaluate the genetic improvement of yield of the herbaceous cotton (Gossypium hirsutum L. var. latifolium Hutch.) in the Brazilian Northeast within the 1976-1994 period. The method used evaluates the yield of genotypes of a year in comparison to the yield of the anterior year in order to calculate the total genetic yield. Media of other cultivars in relation to other characteristics since the beginning of the program up to 1994 are also presented. There was an average rate increase of 1.03% in the yield and improvement in other traits, for example in the percentage of fiber.
